VALVE.

Specification of Letters Patent.

Patented Jan. 4. 1910.

Application filed October 19, 1908. Serial No. 458,382.

To all whom it may concern:

Be it known that I, JOSEPH I). L ivIGXE, a citizen of tlie'lvnitcd States of America, residing at Detroit, in the county ot' Yavne and State of Michigan, have invented certain new and useful Improvements in Valves, of which the following is a specification. reference being had therein to the accompanying drawings. v n

' This invention relates to improvements in valves andincre particularly to improved `means for preventing leakage around the outwardly extending stems ot' radiator and similar valves.

The invention consists in the construction. arrangement and combination of parts as hereinafter more fully set forth, and particularly pointed out in the claims. reference being had to the accompanying drawings, in which Figure l is a transverse vertical section of a device embodying the invention; and Fig. 2 a horizontal section of the same on the line m-.

In the drawing, the invention is shown as applied to a valve construction embodying peculiar means for operating the valve disk for which I have made application for Letters Patent, dated March 23, 1908, Serial VNo. 422.851 but I do not wish to limit myself to such combination, as this invention may beapplied to any valve having a rotatable outwardly extending stem.

As shown in the drawing l is a suitable globular casing having a Valve seat 2 around 'the open inlet end of the casing for a disk valve 3 of any desired form. Screwed into the top of the casing is a plug or bonnet 4 having an outwardly extending tubular portion 5 within which the outwardly extending valve stem 6 is located, and an inwardly extending tubular portion 7 which forms a guide for a cam member 8 having cam surfaces and slots 9 to engageprojecting cam members 10 on the valve stem having similar surfaces. The member 8 is formed with a yoke 11 to which the disk 3 Vis attached by a universal joint 12 and said yoke is provided with studs 13 to engage guide slots in the tubular guide 7 and pre-l vent said member and disk from turning when the stem is turned to engage the cam proJections on the stem with the slots in the 'cam member 8 and lift the disk from its `New the inner pen end of' ai@ tubular membei' 5 is an inwardly extending wall oiledge 14 which forms seats at its upper and lower sides for packing rings 1.3 cf any suitable material and a ange 16 on the valve stein 6 engages the lower side of the lower ring, clamping it between said tlange and its seat.

1T is a hand wheel of wood or other suitable material which is secui'ed to the upper end of a tubular shank 18 by lugs 19 on the shank projecting upward into the wood, the wheel being held in place upon the lues by a disk Q0 engaging the upper side yo the wheel and said disk being secured in place over an axial opening 2l in the wheel by a screw Q2 passing through the disk and engaging a screw-threaded opening in the axis of a plug 23 screwed into the upper end of the tubular shank. This shank downward within the tubular portion .3 of the bonnet and at its inner end seats upon the upper packin ring 15. The bore of the lower end of said shank is square in crosssection and thevalve stem 6 at Q1 is formed to tit said bore so that when the shank is turned by means of the hand wheel the stein will be turned also. The diameter of the bore of said shank is increased at the outer end of its squared portion, forming a seat 25 for a washer Q6 seated thereon within the bore, and a reduced end 27 on the valve stem extends upward in the shank through said washer and is screw-threaded at. its upper end to receive a nut Q8 between which nut and washer a coiled spring 29is sleeved thereon. Said spring 29 exerts a force to hold the flange 16 in Contact with the lower packing ring 15 and the lower end of the shank in contact with the upper ring. thus clamping said rings to `their seats and forming a tight. glan The operation of the spring is not interfered with by the turnin of the hand wheel as the stem and shan turn together and carry said spring.

What; I claim as my invention is 1. The combination with' a casing having a valve seat, a valve disk to engage Asaid seat and a stem to operate said disk, of a tubular member within which the stem projects and slides and is adapted to be turned thereby, a hand wheel on the outer end of said member, a seat surrounding said stem, a flangeon the stem to engage saidseat at its lower side` a shoulder ou the outer end of the stein whollywithin the tubular meina extends gaging the shoulder on the outer end on said stein for holding the spring thereon and engaging said tubular member at its inner end.

Q. The combination with a casing having a valve seat and a valve disk to engage said seat, of a tubular extension on the casing, a seat within said tubular extension, a valve stem for operating said disk' extending outward in the extension past said seat and provided with means for engaging the inner` side of said seat, a hand wheel, a tubular shank to which the hand wheel is secured and extending within t-he tubular extension into engagement with the upper side of said seat and adapted to engage and turn the stem, a nut on the outer end of said stem Wholly within the tubular member and a spring sleeved on the stem between said nut and said shank.

3. The combination with a casing having a valve seat and a valve disk to engage said seat, of avalve stem to operate the disk having a portion which is square in crosssection, a member having a seat surrounding said stern, a hand wheel, a tubular shank to which the wheel is secured, said shank being formed to engage and fit the squared portion of said stem and adapted to engagev said seat at its lower end, a flange on the stern to engage the opposite side of said seat, a washer in the bore of said shank engaging a seat therein and through which washer the stem extends, a nut on the outer end of said stein wholly within the tubular member and a coiled spring sleeved on the stern between said washer and nut. t.

4. The combination with a easing having a valve seat and a. va'lve disk to engage said seat, of a bonnet on the casing having a tubular extension, a Valve stem to operate the disk extending outward in the tubular extension, a seat in said extension surrounding the stem, a flange on the stein to engage the inner side of said seat, a hand wheel having un axial opening, a tubular shank extending within the extension and'engag'ing` the outer side of the seat thereon and engaging the stem to turn the saine, a nut on the outer end of the stem, a coiled spring on the stem between the nut and a shoulder on the shank, a plug in the outer end of said shank, a disk engaging the outer side of the wheel and covering its axial opening, lugs 'on the shank engaging the wheel, and a screw extendingthrou h the disk and engaging a lscrew threa ed opening in the plug.

In testinion whereof I atlix my signature in prence o two witnesses.
